🔒 Your images are never collected. Everything runs locally in your browser and leaves no trace once the page is closed.
BMP is the original Windows bitmap: essentially uncompressed pixel data, which keeps quality perfect and file size enormous. JPG (JPEG) is the universal photo format: lossy compression keeps files small and every device, browser and app can open it.
JPG is the safest possible output: upload portals, older office software, print shops and email attachments all accept it. Converting BMP to JPG also tends to shrink the file noticeably.
How to convert BMP to JPG
- Drop your BMP files into the box above
Or click the box to browse. You can select many files at once — the whole batch is converted for you. - Check that the output format is JPG
This page preselects JPG. Use the Output format menu if you want something else. - Adjust the settings if you need to
Lower the quality for smaller files, raise it for maximum fidelity. Set Max width or Max height to resize; leave both empty to keep the original dimensions. Changes re-convert automatically. - Download the results
Use Download on any single file, or Download all (.zip) to grab the whole batch in one archive.
Good to know
Why convert BMP to JPG
When a file has to travel — email attachment, application form, print shop, upload portal — JPG is the safe choice. Almost nothing refuses it, and the files are small enough to send.
When JPG is the right choice
Photographs, product shots, and images with gradients or lots of colour. Reach for something else when: no transparency; quality degrades a little every time you re-save.
What changes after conversion
Changes to expect: the extension becomes .jpg; camera metadata is stripped; the file usually gets smaller.
Practical tips
- Quality 80–85. Below about 70 you will start seeing blocky artefacts in hair, foliage and smooth gradients.
- Camera metadata (timestamp, GPS position) is stripped during conversion — smaller files, and less to leak.
- Want it smaller still? Set Max width to 1.5–2× the size you actually display, and most web images lose more than half their weight.

Frequently asked questions
Do I have to upload my images?
No. The conversion runs entirely inside your browser, so your files never leave the device — which means contracts, ID scans and client material are all fine to process here. You can even disconnect from the network first; the tool keeps working.
Does converting BMP to JPG reduce quality?
A single conversion at quality 80–85 is visually indistinguishable from the original. What does cause trouble is repeatedly re-encoding and re-saving the same image — that is where loss accumulates.
Can I convert in bulk? Is there a file size limit?
Yes, and effectively no. Because nothing is uploaded there is no server-side size cap — drop in as many files as you like. The only limit is your own memory; images above 120 megapixels are scaled down automatically.
Does it work on a phone?
Yes. Open this page in your mobile browser and tapping the box takes you straight to your photo library. Both iOS and Android work; batch size is limited mainly by how much memory your phone has.
